CHARLES L. HAIGHT, OF POUGHKEEPSIE, NEW YORK, ASSIGNOR TO THE EAGLEHORSE SHOE COMPANY, OF WVISCONSIN.

HORSESHOE-FORMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 539,427, dated May 21,1895.

Application filed July 27, 1892. Serial No. l ls N 111 1 To all whom itmay concern.-

Be it known that 1, CHARLES L. HAIGHT, of

- Poughkeepsie, in the county of Dutchess and State of New York, haveinvented certain new and useful Improvements in Horseshoe-FormingMachines; and I do hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it pertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

The main object of my invention is to facilitate the production ofhorse-shoes and reduce the cost thereof.

It consists of certain novel features in the construction andarrangement of parts hereinafter particularly described and pointed outin the claims.

In the accompanying drawings like letters designate the same parts inthe several fig- UI'GS.

Figure l is a plan view of a machine embodying my improvements, theslide-retaining cap-plates being removed. Fig. 2 is a side elevation ofthe machine. Fig. 3 is an end elevation viewed from the left withreference to Figs. 1 and 2. Fig. 4 is a vertical crosssection on theline a: to, Fig. 2, looking from the right. Fig. 5 is a perspectiveview, on an enlarged scale, of one of the swage-slides and Fig. 6 is asimilar view of the forming-die as seen from the under side.

A is a reciprocating slide, movable horizontally in ways provided for itin the frame N. It is connected at one end by a rodor pitman a, with thecrank b, on crank shaft B, by which it is actuated. To the oppositeendof said slide is rigidly and detachably secured by a bar 0, theforming die 0, the contour of which corresponds with that of the innercurved edge of the shoe it isintended to form. On the upper side saiddie is formed with ribs 0 0', between which the bar 0 is bolted andsecurely held, and around its edge it is .formed with anoutwardlyprojecting flange 0 which holds the blank in place, preventing itsupward deflection and displacement while it is being formed into a shoe.

D D are two horizontally reciprocating slides movable parallel withtheslide A in suitable ways in frame N and provided at one end with swagingdies 61 d, which are held in recesses therein by plates d 01 screwed tosaid slides. The slides A and D D are held in place in their ways inframe N by cap plates 11. n

. move a limited distance vertically, the enlargements e e turning inthe recesses in which they are held.

Upon a horizontal shaft F supported in brackets f on the base of themachine frame N, are mounted two bell crank levers G G, the upwardlyprojecting arms of which bear loosely against the friction rollers e e.The horizontal arm g of each of said levers is provided on the underside of its free end with a friction roller g, in range with a cam H ona rotary cross shaft 1. 7

Each slide D is formed in its upper side with a T-shaped recess in whichis inserted and held the similarly shaped flattened end of a rod J,supported horizontally in bearings in frame N and provided with aspiralspring j, bearing atone end against a nut thereon and at the otheragainst the frame.

Opposite the dies d cl, two dies It is, are adjustably held transverselyto the movement of slide A against abutments K on frame N by cap platesis At the opposite end of the machine from the crank shaft B on oppositesides of the path of the die 0, are two lovers L L, fulcrumed atintermediate points therein on pins ZZ, secured vertically to frame N.Said levers are provided at opposite ends with ben'ding rollers Z Z andfriction rollers Z Z The pins on which the rollers Z Pare journ'aled,pass through transversely slotted openings in levers L L, and areadjustably held therein.

Aand die 0, is aslide M,to which is attached IOO adjacent to rollers Z Za wedge block on. A screw threaded striking rod m is adjustably held bynuts m in upturned perforated ears on the upper side of said slide M, inline with the bar 0.

A spring Z connects the levers L L between the fulcrum pins Z Z androllers Z Z and holds said rollers in engagement with the oppositeinclined or curved sides of the wedge block m.

represents the driving shaft provided with a suitable pulley o, and witha pinion 0', which engages on one side with a gear P on crank shaft 13and on the other with a gear Q on cam shaft I.

It will be observed that the several shafts B, F, I and 0 have theirbearings firmly and rigidly supported either upon the base or top offrame N, in such a manner as to most efficiently resist the strain towhich they are subjected.

Channels 17. n, are formed in the frame N between the dies (Z d and 7.:713, to receiveand conduct off scales loosened from the blanks and toprevent accumulation of such scales and consequent clogging of themachine.

My improved machine operates as follows: The driving shaft 0 beingrotated in the direction indicated by the arrow in Fig. 2, turns thecrank shaft B and cam shaft I through the intermeshing pinion o andgears P and Q in opposite directions also indicated by arrows in thesame figure. The forming die 0 attached to slide A is thus driven backand forth between the inner ends of the dies 7t 70, and the rollers Z Zin the adjacent ends of levers L L, by the crank b and connecting rodct; and the dies d d, attached to slides D D are moved toward and. fromthe opposing dies 7t) 70 by the joint action of the cams I-I, bell cranklevers G G, and the retracting springs jj on rods J J. The blanks orbars of iron of the proper length and size are placed as indicated bydotted lines in Fig. 1, one at a time crosswise upon a leaf or table non frame N, with their ends between the dies dd and 7c k, which closingagainst the blank R as shown in Fig. 2, swage and form the heels of theshoes. The forming die 0 then advancing forces the blank between theinner ends of dies 70 k, which bend it around said die (3. The bar 0,striking the adjacent end of rod m on slide M, forces the wedge block inforward between the friction rollers Z Z thereby moving the bendingrollers Z Z at the opposite ends of levers L L toward each other againstthe outeredges of the shoe and bending the heels inwardly against thecontracted sides of the forming die (J, thus completing the shoe withthe exception of the calks, nail holes and groove. When the slide A isWithdrawn, carrying the bar 0 out of contact with rod m the spring Zspreads the ends of levers L L, carrying the bending rollers Z Z anddrawing the friction rollers Z Z together against the inclined or curvededges of the wedge block m, forces the slide M backward intoits normalposition. As the forming die 0 passes backward the shoe is removed anddrops therefrom through an 'opening in the bed of the machine.

The friction rollers e e connected by the vertically swinging rollerblocks E E with slides D D, prevent friction between said slides and thebell crank levers G G, due to the arc motion of said levers and causethe machine to run with greater ease and less wear.

By the substitution of dies of different shapes and sizes and by theproper adjustment of such dies and of the friction rollers Z Z andstriking rod 117/, shoes of various sizes and shapes may be made by themachine.

Various changes in the details of the machine may be made within thespirit and intended scope of my invention.

In a horseshoe forming machine, the combination with areciprocating forming die, of levers fulcrumed at points between theirends to the frame on opposite sides of the path of said forming die andprovided at one end with bending rollers, a reciprocating wedge blockmovable independently of and in line with said forming die between theopposite ends of said levers to close said bending rollers against ablank on said forming die, and a spring connecting said levers andholding them in engagement with opposite sides of said wedge block,substantially as and for the purposes set forth.
